Question

What are the standard conditions under which reduction potentials are measured? 1°C and 1 M reactants 25°C and 1 M reactants 25°C and 2.5 M reactants 1°C and 25 M reactants

Answer 1

It relates the measured cell potential to the reaction quotient and allows the ... Substituting these expressions into Equation 20.6.1, we obtain ... the standard cell potential (E° cell), and the reactant and product concentrations at ... 0.013 M, [Ce3+] = 0.60 M, [Cl−] = 0.0030 M, PCl2 = 1.0 atm, and T = 25°C.

Answer 2

25°C and 1 M reactants

Step-by-step explanation:

The standard conditions to measure the reduction potential as standard electrode potential is 298.15 K temperature (25°C) and 1 mol / L concentration of each reactant.

The pressure should be 1 atm for gaseous reactants (like in case of Standard hydrogen electrode where pressure of hydrogen gas is taken to be 1 atm).
